Layer 1 ( CCITT ) ITU-G703 defines the physical and electrical interface.

* The R interface defines the point between a non-ISDN device and a terminal adapter ( TA ) which provides translation to and from such a device.

The monolithic differs from other operating system architectures ( such as the microkernel architecture ) in that it defines alone a high-level virtual interface over computer hardware, with a set of primitives or system calls to implement all operating system services such as process management, concurrency, and memory management itself and one or more device drivers as modules. Structure of monolithic kernel, microkernel and hybrid kernel-based operating systems

POSIX defines the application programming interface ( API ), along with command line shells and utility interfaces, for software compatibility with variants of Unix and other operating systems.

The SCSI standard defines command sets for specific peripheral device types ; the presence of " unknown " as one of these types means that in theory it can be used as an interface to almost any device, but the standard is highly pragmatic and addressed toward commercial requirements.

In addition to providing users with a language and a platform-neutral remote procedure call ( RPC ) specification, CORBA defines commonly needed services such as transactions and security, events, time, and other domain-specific interface models.

The X. 25 specification defines only the interface between a subscriber ( DTE ) and an X. 25 network ( DCE ).

X. 75, a very similar protocol to X. 25, defines the interface between two X. 25 networks to allow connections to traverse two or more networks.

An ABI should not be confused with an application programming interface ( API ) which defines a library of routines to call, data structures to manipulate, and / or object classes to use in the construction of an application using that particular ( often language specific ) API.

IEEE 802. 3ab, which defines the widely used 1000BASE-T interface type, uses a different encoding scheme in order to keep the symbol rate as low as possible, allowing transmission over twisted pair.

VESA BIOS Extensions ( VBE ) is a VESA standard, currently at version 3, that defines the interface that can be used by software to access compliant video boards at high resolutions and bit depths.

The standard defines two interface levels ; the physical level that deals with electrical signals, connectors, mechanical and thermal conditions and the logical level that describes the address space, data transfer protocols, cache coherence mechanisms, synchronization primitives, control and status registers, and initialization and error recovery facilities.

* ( optional ) defines an interface for accessing a component's parent in the recursive structure, and implements it if that's appropriate

The MOP defines a standard interface to the underpinnings of the CLOS implementation, treating classes, slot-descriptions, generic-functions and methods themselves as instances of metaclasses, and allows the definition of new metaclasses and the modification of all CLOS behavior.

In computing, a locale is a set of parameters that defines the user's language, country and any special variant preferences that the user wants to see in their user interface.

The IVI Foundation defines a standard driver application programming interface ( API ) for programmable instruments.

A major problem with marker interfaces is that an interface defines a contract for implementing classes, and that contract is inherited by all subclasses.

These simple opcodes are then constructed by the user into an instrument ( usually through a text-based instruction file, but increasingly through a graphical interface ) that defines a sound which is then " played " by a second file ( called the score ) which specifies notes, durations, pitches, amplitudes, and other parameters relevant to the musical informatics of the piece.

Thus a virtual instrument can either be run as a program, with the front panel serving as a user interface, or, when dropped as a node onto the block diagram, the front panel defines the inputs and outputs for the given node through the connector panel.

For instance, Paul Sherman of the Absolute Linux distribution defines " lightweight -- meaning 2 things: that it can run on older hardware and that the OS interface stays out of your way.

This approach can be pushed to the limit of defining interfaces with a single method ; e. g. the Java language defines the interface < tt > Readable </ tt > that has the single method and a collection of implementations to be used for different purposes, among others: < tt > BufferedReader </ tt >, < tt > FileReader </ tt >, < tt > InputStreamReader </ tt >, < tt > PipedReader </ tt >, and < tt > StringReader </ tt >; or even less, marker interfaces like contain virtually nothing.
